Correct.

the v27.fw file does contain the correct firmware, so the fact that the
inkernel tuner driver isn't select the correct version (or that it needs
a hint in the config struct) is probably a very small fix.
Mauro (cc'd) generally maintains that driver and he should be able to
help. My suggestion is that you cut/paste the attach/config struct from
your leadtek code into this email thread. From you email address I guess
you're trying to get DVB-T 7MHz working in Australia. Mauro can review it.
Ideally, we'd point you at a different card struct for the same tuner
that we know works in Australia, so you build the leadtek config struct
based on something that we know works.
Mauro, what should the attach/config struct look like for a xc2028/3028
tune in Australia? Can you point to a working example or suggest a change?
